Health hazard control methods, work processes, and existing control technologies used in the manual transfer of chemical powders were evaluated at Porcelain Metals Corporation, Louisville, Kentucky in May, 1984. The company employed 97 workers involved in the manufacture of porcelain and metal stampings. The major dry ingredients were frit, silica, and clays. Raw materials were received in bags that were opened as needed and dumped directly into a hopper. The material was discharged into a mill, and various amounts were dispensed by scoop into a pan for weighing. The pan contents were then dumped into the hopper, the mill head was attached, and water was added. After milling, the slurry was pumped to a storage tank for later use. General exhaust ventilation was used, and hearing protectors, safety glasses, hard hats, and dust masks were provided. Workers were encouraged to use good work practices, and were given pre-employment physicals and annual hearing tests. Periodic atmospheric dust sampling was performed, and monthly inspections were conducted. The author does not recommend an in depth study of control technologies at this company since no unique control methods are used.
